USB interfaced I/O card for downloading configuration options

Mesa's 7I61 is a USB interfaced version of the FPGA based Anything I/O card series. It provides 96 I/O bits of easy to access programmable user I/O.


The 7I61 is a USB interfaced version of Mesa's FPGA based Anything I/O card series. It provides 96 I/O bits of easy to access programmable user I/O.

The USB port is used for downloading initial configurations either directly to the FPGA or to the on-card Flash EEPROM for stand-alone FPGA configuration. After configuration, the high speed USB port can be used for 7I61 host communication. The 96 I/O bits are available on four 50 pin connectors, 24 bits per connector. The 50 pin connectors have I/O module rack compatible pinouts. All I/O pins have pull-up resistors and are 5 V tolerant.

Several I/O interface daughter cards are available for the 7I61. The daughter cards include 4, 6 , and 8 channel analog servo amp. interfaces, 6 channel resolver interface, RS-422/485 interfaces. 2 daughter cards can plug directly onto the 7I61, and a maximum of 4 daughter cards per 7I61 are supported.

Many IO configuration files are provided with the 7I61 including simple remote I/O, smart remote I/O, 4 to 16 axis servo motion control, 4 to 48 axis stepper motor control, multiple channel PWM generator, arbitrary waveform generation, quadrature counters, resolver interface, mutliple timers and more. VHDL source is provided for all configurations.
